Vodacom's bad customer care

Since Jule 2017 have I tried to have contracts cancelled with some success but debit order from a contract is still running one contract has been cancelled and paid twice. The problem however is that since August 2018 I have tried to rectify the situation but to no avail. I am been send from pillar to post. I started with retentions and ended up with customer services but no joy. I have send correspondence and proof of what I am saying to customer services on numerous occasions with no reaction . When I follow up the whole process starts again with an automated email and a new consultant who says the same thing "please send proof" which I do but no response back. I have even had a vodacom consultant phoning me overseas who faithfully promised to assist if I send him the documentation again still no luck Part of the problem is that the customer does not deal with one consultant but every time gets another constultant

I am residing overseas which makes the situation worse

If we talk about a bad experience well this is it and it seems that the word "customer care' does not exist in Vodacom's vocabulary.
